Quick start

Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
Allow inbound SSH (22) for yourself plus the application port(s): 5432 (PostgreSQL) — to your application subnets only — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
Connect locally with `sudo -u postgres psql`, or over TCP as postgres with the generated superuser password (see First login below).
Set listen_addresses and a pg_hba.conf rule for your subnets, restart PostgreSQL, then open 5432 in the NSG to your app tier only.

Get your admin password (one time)

ssh <your-username>@<VM-IP>
sudo cat /var/lib/pgsql/.superuser-password

Sign in as postgres — either with `sudo -u postgres psql` (peer authentication) or with the generated password in /var/lib/pgsql/.superuser-password over TCP. Change the password and create a least-privilege application role before you open 5432 to anything.

Common use cases

Transactional workloads on a RHEL-compatible base
Analytics and reporting databases
Geospatial workloads with PostGIS
On-prem PostgreSQL lift-and-shift
